Abstract

The invention relates to dispersants or their salts, comprising A the reaction product of one or more polyisocyanates with a mean functionality from 2.0 to 5, with B at least one monohydroxyl compound, C at least one dicarboxylic acid compound, and D a compound which contains at least one basic ring nitrogen as well as an isocyanate-reactive group, of the isocyanate groups about 30-70% having been reacted with B and C together and about 30-70% having been reacted with D. i
